I wrote this to one of our other members... The 2012 v6 has a new engine called the LFX. The main difference between the two LFX/LLT is that the LFX has one big pipe on each side that air passes through on it's way to the exhaust. The 10-11 model v6 (LLT) has a set of three pipes on each side. The other small difference in the engine is a new maf (mass air flow) censor for the 2012. This is why company's are needing to update there intakes to the new maf. Cold air Inductions is the only company to do it. Also since there are differences to the undercarriage of the convertible, cat back exhausts need to be updated as all current models wont fit.
